I suspect "ruby" is given primary billing for these rocks because of its likely appeal to potential buyers despite the fact that, considering the relative volumes of these components in these rocks, it would seem more appropriate for zoisite to be given top billing.

Ruby-zoisite， ruby in zoisite， ruby-in-zoisite 红宝黝帘石的名字和 anyolite 的名字在市场也经常使用，将红宝的名字作为主角突出出来，主要是为了吸引潜在的买主，尽管矿物事实上有与红宝相似的大量成分，但更多的是黝帘石。

The high temperature and high pressure experiments show that the strength of rocks is very high in earthquake source (mainly granitic rocks, such as adamellite), which could sustain great different stress and accumulate huge energy. This is one of major causes for high-angle reverse fault slip and high intensity of Wenchuan earthquake.

岩石破裂-黏滑-摩擦实验表明，以二长花岗岩为代表的震源区岩石具有很高的破裂强度和摩擦强度，能够承受极大的差应力和积累巨大的能量，这是高角度逆断层能够滑动和汶川地震强度大的原因之一。

Recently, a nearly E-W-striking, over 10 km long albitite zone has been recognized for the first time in the Lower Silurian Meiziya Formation in a Lower Paleozoic lead-zinc ore deposit concentration area of the Xunyang basin, South Qinling. It shows a conformable contact and gradational relationships with the country rocks and has thick-bedded and massive, banded, brecciated structures and fine and very fine equigranular and intraclastic textures. It is chemically characterized by enrichment in SiO2, Al2O3 and Na2O and is rich in the trace elements Fe and Mn and poor in the trace elements Co, Ni and Cu. Its ∑REE, LREE and HREE are lower than those of the country rocks and exhibit pronounced Eu depletion.

最近，在南秦岭旬阳盆地下古生界铅锌矿集区内的志留系梅子垭组地层中首次识别出一条近东西方向延伸长达10余千米的钠长石沉积岩带，与地层整合产出，渐变过渡，厚层块状，条带状，角砾状构造，均粒微-细晶结构，内碎屑结构；其化学成分以富含SiO2，Al2O3及Na2O为特征，富Fe，Mn，贫Co，Ni，Cu等微量元素；该钠长石岩的∑REE，LREE，HREE均较围岩偏低，具明显Eu亏损的特征。

Toppling failure always occurs in anaclinal slopes of layered rock mass, such as thin-bedded sedimentary rocks, foliated metamorphic rocks and those of one single joint set.

倾倒破坏通常发生於层状岩体之逆向坡，如薄层沉积岩、叶理状变质岩及其它含有单组节理之岩石。

The host rocks mainly are meta andesitic dacitic volcanic rocks.

谱线特征为马鞍型，其底坪年龄为石英的结晶年龄。

In addition, the features of elemental geochemistry of all samples suggest that (1) the EarlyTriassic andesitic rocks, characterized by characteristic natures of island arc volcanics, likely erupted in the subduction setting; that (2) the generation of LateTriassic rhyolites with an affinity of Alike granite and synchronously main body granites in the Lincang batholith displaying similar geochemical features, is closely related with the postcollision or latecollision setting; that (3) although the LateTriassic basic rocks partly show island arc volcanics such as highAl contents and NbTa depletion, some of them possessing highMg contents and mostly having traceelement ratios similar to intraplate basalt, which indicates that they erupted in the postcollision rift environment.

元素地球化学特征表明，早三叠世火山岩具有典型的岛弧火山岩的特征，暗示其很可能形成于俯冲的构造环境；中三叠世晚期的流纹岩与临沧花岗岩基主体具有非常相似的地球化学特征，结合其流纹岩具有A型花岗岩属性，表明该区中三叠世火成岩形成于碰撞后的构造背景；而晚三叠世基性火山岩虽然在地球化学特征上显示出与岛弧火山岩相似的高铝和NbTa的亏损，但其中部分火山岩具有高镁和板内玄武岩的微量元素比值特征，说明这些火山岩可能形成于碰撞后裂谷环境。

Meanwhile, the volcaniclastic rocks were modificated by the thermal fluid activity, for example, sericitization of plagioclase, chloritization of volcanic detritus in andesitic detris tuff; in the tufaceous mud, the thermal fluid activity accelerates "maturating" of the organic carbon by heating; and the trace elements show an anomaly in the wall rocks.

同时，受热流体活动的影响，热流体对火山碎屑岩具有一定改造作用，如在安山质岩屑凝灰岩中，斜长石绢云母化、火山岩岩屑绿泥石化明显；在凝灰质泥岩中，热流体对围岩中有机碳具有明显的&催熟&加热作用，微量元素则出现异常现象。

The changing rocks are the embodiment of Lou Quanmu's art:seemingly carefree but intrinsically restrained. In a statement Lou said:"Mountain rocks possess forms that are both abstract and figurative, their shapes are paralleled to our mental topology, and their apertured, coarse textures are like our nerves."

罗荃木对山石的想法表现了对艺术的追求，作品既自由又抑郁，即同其述：「山石是介于抽象和具象之间的形象，可以按照内心的感觉自由行走，在任何地方多一点或少一点，不被形所限制，山石的型态有点像心灵的地图，布满奇怪的洞穴，它的肌里几乎是神经质的」。
